FIBERGLASS PETROLEUM TANKS FOR UNDERGROUND STORAGE

FIBERGLASS PETROLEUM TANKS FOR UNDERGROUND STORAGE

WHY OUR TANKS ARE YOUR BEST INVESTMENT In the early 1960s, the American Petroleum Institute challenged Containment Solutions, Inc. (CSI) to develop a rustproof underground storage tank that would be safe and strong enough to satisfy the petroleum industry s most stringent long-term storage demands. Our engineers accepted the challenge and pioneered the underground fiberglass tank technology. Our innovative design work resulted in the UL 1316 specification which governs underground fiberglass tank manufacturing. Major oil companies have responded to our achievement by specifying fiberglass tanks for approximately 95% of their underground fuel storage installations. Their keen awareness of the limitations of a steel tank in a corrosive environment and their confidence in fiberglass tank technology has helped us earn a reputation for safe, rust-free, long-term underground storage. More than 45 years and 300,000 tank installations later, we continue to improve upon those processes utilizing today s automation to develop new applications and products. What started from petroleum storage needs has expanded into the handling of lubrication oils, water, waste water and alternative biofuels such as ethanol and biodiesel. Containment Solutions is proud to be the largest American fiberglass tank manufacturer.

SUPERIOR AUTOMATED PROCESS TANKS COMPATIBLE WITH BIO FUELS AND ETHANOL AUTOMATED MANUFACTURING PROCESS We use steel mandrels (cylindrical molds) to build our tanks from the inside out. The molds provide a firm and consistent surface upon which we apply materials to make our tank. The rotating mandrel and the application of the materials are controlled by a computer, custom designed to manufacture underground tanks. As the mandrel rotates; resin, glass and specially treated silica are precisely metered onto the mandrel from above. Tank thickness is determined with an instrument that magnetically senses the metal mold surface through the fiberglass reinforced plastic laminate. This method accurately measures the thickness of the laminate using specific points all over the surface of the tank wall and is more exact than the ultrasonic methods used by other manufacturers. The result is a closely controlled process and a very consistent tank wall composition providing uniform integrity. DIFFERENT PROCESS, BETTER RESULTS The inside-out approach to manufacturing tanks, is a superior process with unique advantages. Inner Surface: The initial material forming against the steel mold produces an incredibly smooth finish, free of surface variations. The inside surface in our process is not exposed to air as it cures thus eliminating air inhibited cure issues. The result is a well cured, high gloss inner surface without the need for additional interior liners. Other manufacturing methods rely on inferior hand sprayed wax coatings to combat surface cure problems. Outer Surface: Exterior stiffening ribs are applied in optimal locations and constructed of the most efficient reinforcing materials. We can also modify a tank by adding filament winding glass in tension, glass woven roving, glass mat, or any other materials in specific locations on the outside of the tank wall. Our entire shell wall surface is manufactured with the same corrosion resistant resin. With our homogeneous tank shell, you can be assured the exterior surface has the same petroleum resistance capabilities as the interior surface. We do not use liners or special coatings on any tank surface. Another important advantage of our inside-out manufacturing process is a consistent inner diameter. Using a mold as a frame insures a set dimension and capacity. If additional tank wall is necessary, we simply add thickness to the outside surface. In contrast, an outside-in process by definition relies upon a fixed outer diameter and variable inner diameter. To add thickness using this process, glass is applied to the inner surface sacrificing maximum tank capacity. Simply put, our process allows for a more versatile and dependable product. 3 MANUFACTURING PROCESSES

EXTENSIVE ANALYSIS Containment Solutions commitment to excellence begins in the Research and Development Center. No other tank manufacturer has invested the amount of time and resources, to not only product development but product enhancement. Our engineers use the latest technology to analyze tank compatibility for alternative fuels and unique fluids like Urea DEF. For our experts, tank testing is a science measured in decades. We focus our talents on pushing the limits of what is possible. ENGINEERED AND TESTED CORROSION RESISTANCE The Containment Solutions tank wall is composed of resin, glass and a specially treated silica that together result in a composite matrix that is compatible with petroleum products including: All Octanes of Gasoline Jet Fuel AV-Gas Motor Oil Kerosene Diesel and Bio-Diesel Fuel Fuel oil All blends of Ethanol and Methanol up to 100% Oxygenated Motor Fuels and more Containment Solutions instituted and perfected the use of a specially treated silica in our laminate matrix. The addition of the silica has been proven to enhance the performance of our laminate. Our exclusive laminate has been thoroughly tested to meet the requirements of UL 1316 and CUL S-615. Long-term corrosion and material properties testing is done at our Research and Development Center (R&D). Laminate testing includes current fuels, blends and other oxygenates, but we do not stop there. We also test alternative products and blends that could be stored in our tanks in the future; as fuel options change, your storage tank compatibility will not. Many of the newest industry fuels and bio fuels are alcohol based. Alcohol blends, including ethanol, increase the likelihood of water in a storage tank, resulting in rust and microbial-induced corrosion (MIC) in steel tanks. The inherent non-corrosive nature of a fiberglass CSI tank eliminates the possibility of rust on all tank wall surfaces. Extensive corrosion testing allows us to confidently offer an industry leading 30-year warranty while most steel tank manufacturers have reduced their warranties to 10 years. CSI R&D has authored patents and expert reports introducing cutting-edge products like double-wall sumps and the first Urea DEF underground chemical tank. Since the first non-corrosive tank was designed back in the 1960s, we have maintained the highest quality standards and have utilized advanced technologies to engineer and build the world s premier fiberglass storage tank. RESEARCH AND DEVELOPMENT 4

DOUBLE-WALL TANKS CSI s advanced double-wall technology gives storage tank owners, municipalities, counties, provinces, and states proven protection against petroleum contamination of underground water supplies. In addition to our UL listing, our tanks comply with the EPA s recommendation for secondary containment systems wherever underground tanks are located near underground water supplies. Containment Solutions double-wall tanks give you two levels of protection, so you have twice the assurance and twice the risk management that any single-wall tank can offer. The primary tank is designed to contain your fuel. In the unlikely event that there is a breach in this wall, the secondary wall is designed to contain your product and prevent seepage into the environment. HYDROSTATIC MONITORING For the most effective double-wall storage tank protection, we recommend hydrostatic monitoring. The cavity between the inner and outer tank walls (interstitial space), as well as a factory mounted reservoir, is filled with a non-toxic colored brine solution. Hydrostatic pressure is continuously applied to the interstitial space, enabling monitoring of the primary and secondary tanks. An electronic sensor in the tank reservoir will send an alarm if the brine level changes beyond a predetermined level. The CSI Hydrostatic Monitoring System offers a leak detection capability superior to other methods because of our unique tank construction. The independent tank wall design ensures that 100% of the primary and secondary tank walls are in contact with monitoring fluid. This open environment allows brine to move freely through the interstitial space, unimpeded by glass fabric bonded to the tank walls typically used in competitive designs. Since the unblocked interstitial space does not hinder communication, the CSI Hydrostatic Monitoring System is fast and effective. HYDROSTATIC MONITORING detects leaks in either the primary or secondary tank walls in all installed conditions. NORMAL CONDITIONS The reservoir liquid level will be stable if both the inner and outer tank are tight. The reservoir sensor will activate an alarm if the reservoir drains or overfills. INNER WALL BREACH Monitor fluid drains into the primary tank causing the reservoir to drain. The petroleum product remains safely contained in the primary tank.

SUPERIOR PROTECTION WITH HYDROGUARD The HydroGuard System is the most dependable storage system available. HydroGuard combines the UL listed double-wall tank and double-wall tank sumps for a complete hydrostatically monitored storage system. HydroGuard also comes with a deadman anchoring system, completing the underground storage solution. As the name suggests, the HydroGuard System utilizes hydrostatic pressure to provide a proven means of monitoring for leaks 24 hours a day, 7 days a week. In fact, our hydrostatic monitoring system has been certified as a continuous leak detection system by the National Work Group on Leak Detection Evaluations, (NWGLDE). Unlike typical storage systems, HydroGuard provides 360 secondary containment of not only the stored product in the tank but the critical piping components above the tank. CSI s double-wall tank sumps are state-of-the-art including built-in brine reservoirs and street accessible reservoir sensor housing. The turbine and fill/vapor sumps are continuously monitored for the ultimate in underground fuel storage protection. The HydroGuard System was designed to exceed the most stringent regulations and storage requirements, like California s AB 2481; and also comes with our 30-year structural and corrosion warranty. The HydroGuard System is a complete hydrostatically monitored double-wall storage system. OUTER WALL BREACH If the groundwater is below the tank top, the non-toxic monitor fluid drains into the ground causing the reservoir to drain. HIGH GROUNDWATER If the groundwater is over the tank top, the reservoir will overfill with groundwater and activate the high level alarm on the reservoir sensor.

ADDITIONAL STORAGE OPTIONS Every installation is unique, sometimes involving single-wall tanks, triple-wall tanks, or compartment tanks. Containment Solutions has a complete range of products and accessories to meet our customer s needs. SINGLE-WALL TANKS The very first fiberglass underground petroleum storage tank was a single-wall design and for 45 years single-wall tanks have been installed around the world. CSI single-wall tanks use the same manufacturing methods and laminate matrix as our double-wall designs, compatible with standard fuels as well as alternative fuels such as biodiesels and all blends of ethanol. Existing single-wall tanks can be upgraded or modified to meet changing standards and storage requirements. For more information on our extensive enhancement services, see the CSI Field Services section of this brochure or contact a sales representative today. TRIPLE-WALL TANKS In 1997, CSI designed the first UL listed triple-wall fiberglass tank for use in environmentally sensitive areas where tertiary containment is required. Triple-wall tanks offer three levels of protection: the proven strength and performance of a primary fiberglass tank, and in the unlikely event that there is a breach, secondary and tertiary walls designed to contain the fuel and prevent any spill into the environment. Triple-wall petroleum tanks, like single and double-wall models, come with a standard 30-year structural and corrosion warranty. SINGLE-WALL RETAIL INSTALLATION TRIPLE-WALL STORAGE 11 ADDITIONAL STORAGE OPTIONS

COMPARTMENT TANKS Compartment tanks are built by dividing a storage tank with a single-wall or double-wall bulkhead, creating two or more independent storage areas. They are a popular choice for retail petroleum marketers interested in storing multiple blends of fuel, including diesel. Since compartment tanks can be divided to accommodate two or more grades of fuel, they allow the site designer to plan for any ratio of fuel storage. These tanks are often used for sites where property is limited and installing multiple tanks is difficult. The design versatility of a CSI compartment tank can meet unique customer requests as well as local requirements. Standard double-wall compartment tanks consist of one bulkhead but complex designs can include additional bulkheads forming multiple storage areas. This compartment tank includes 2 bulkheads, an alternative in this limited space to installing 3 individual tanks. DOUBLE-WALL COMPARTMENT TANK WITH DOUBLE-WALL BULKHEAD DOUBLE-WALL BULKHEAD ANNULAR SPACE FRP RESERVOIR COMPARTMENT B BENEFITS OF COMPARTMENT TANKS Reduced shipping costs with fewer tanks Fewer labor hours during installation with fewer tanks Smaller excavation sites needed for fewer tanks Site is more adaptable to changing consumer demands COMPARTMENT A ADDITIONAL STORAGE OPTIONS 12

FIBERGLASS TANK SUMPS Protecting your storage system and the surrounding environment includes protecting the components that connect to the tank. Pumps and piping often require annual or semi-annual maintenance and testing. Without a sump, buried components are difficult to access and service. Tank sumps are protective enclosures for pumps, piping and other accessories above the tank top. CSI provides a full line of fiberglass tank sumps in round and polygon designs, available in 42 or 48 diameter. CSI sumps can be ordered in single or double-wall construction, the same as our tanks. 34 Lid O.D. For nearly 20 years CSI has been perfecting the tank sump design and installation process, creating the most reliable and contractor friendly sump line available. Our proven technology has been utilized in thousands of installations. CONTAINMENT COLLARS The protection of storage system components above the tank top begins with the containment collar. CSI containment collars are factory bonded to the tank wall, and engineered to fit the single or double-wall tank sump specified. The collars feature a built-in adhesive channel making field bonding installation easier than ever. Watertight Lid Enclosure Top Round Body Extension Field Bonded Adhesive Joint Polygon Body (8- Flat Panels) Field Bonded Adhesive Joint Containment Collar 32 ¾ Neck O.D. 32 I.D. 16 42 or 48 I.D. 19 2 0 L 4-7 4½ SINGLE-WALL TANK SUMP WITH WATERTIGHT LID CSI tank sumps are manufactured and shipped as individual components such as sump bodies, enclosure tops and adhesive kits. Each sump is then assembled in the field. This process requires that every component be clearly identified with the UL mark. Our assembled sump system, including the adhesive, is UL listed; the only one of it s kind in the market place. The exclusive listing signifies that our tank sump designs meet the high quality standards expected from UL and CSI. 13 ACCESSORIES

TANK SUMP LIDS Turbine tank sump lids are used at the submersible turbine end of the tank when access is infrequent and the area must be watertight. The turbine lid is made of rigid fiberglass and fits into place by simply pushing down on the lid. Comfort grip handles make removal of the lid convenient. Fill/Vapor tank sump lids are available for the fill-end of the tank when multi-port manholes are used. We offer two access opening options to accommodate the most popular shroud boots and spill containment systems. Both configurations include an observation port allowing easy access for internal sump inspections. Turbine Lid Fill/Vapor Lid w/ 15 Access Openings Fill/Vapor Lid w/ 13 Access Openings WATERTIGHT TESTED Lid assemblies are tested to 1 of hydrostatic head pressure to ensure a watertight seal. Access and removal of lids is possible through a standard 36 street box. CSI tank sumps are UL listed and carry our comprehensive 30-year structural and corrosion warranty. 100% SECONDARY CONTAINMENT Several competitive products bond the sump walls together using glass fabrics. CSI Double-wall tank sumps are built with two completely independent walls. This open environment offers the perfect communication pathway for hydrostatic monitoring which means true 360º protection. WATERTIGHT DEPENDABILITY An alternative to the traditional lay-up, the unique CSI adhesive channel facilitates a permanent and watertight joint which protects against leaks. The no mess installation is an easier and more effective way to ensure a watertight connection. DOUBLE-WALL TANK SUMP JOINT SINGLE-WALL TANK SUMP JOINT ACCESSORIES 14
